Question

我使用来自github的MPandroid图表库，这是我的应用程序中的lib链接MPANDROID来绘制一些图表，但问题是条的高度，我有 YValue1 = 81 ， YValue2 = 97 ， YValue3 = 91 ， YValue = 86 但是条形图非常小!!

private void setBarChart(BarChart mChart, DashboardMCOP mcop, DashboardMCOM mcom)
    {
        mChart.setOnChartValueSelectedListener(this);

        mChart.setDrawBarShadow(false);
        mChart.setDrawValueAboveBar(true);
            mChart.getDescription().setEnabled(false);
        mChart.setMaxVisibleValueCount(100);
        mChart.setPinchZoom(false);
           mChart.setDrawGridBackground(false);  
        IAxisValueFormatter xAxisFormatter = new DayAxisValueFormatter(mChart,context );
        XAxis xAxis = mChart.getXAxis();
        xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
        xAxis.setDrawGridLines(false);
        xAxis.setGranularity(1f); // only intervals of 1 day
        xAxis.setLabelCount(7);    
        xAxis.setValueFormatter(xAxisFormatter);    
        YAxis leftAxis = mChart.getAxisLeft();
        leftAxis.setEnabled(false);  
        YAxis rightAxis = mChart.getAxisRight();
        rightAxis.setEnabled(false);
        Legend l = mChart.getLegend();
        l.setEnabled(false);
         XYMarkerView mv = new XYMarkerView(context, xAxisFormatter);
        mv.setChartView(mChart); // For bounds control
        mChart.setMarker(mv); // Set the marker to the chart
        mChart.animateY(1400, Easing.EasingOption.EaseInOutQuad);
        setDataBar(mChart, mcop, mcom);

    }

我在条形图中设置数据的功能

 private void setDataBar(BarChart mChart, DashboardMCOP mcop, DashboardMCOM mcom)
    {
        ArrayList<BarEntry> yVals1 = new ArrayList<BarEntry>();

        int id = mChart.getId();

        String viewName = getResources().getResourceEntryName(id);
       if(viewName.equalsIgnoreCase("barchartMCOM1")) {
            if(mcom != null) {
                yVals1.add(new BarEntry(0, mcom.getTreat()));
                yVals1.add(new BarEntry(1, mcom.getContract()));
            }

        }     
        BarDataSet set1 = null;
                set1 = new BarDataSet(yVals1, "");

            set1.setColors(ColorTemplate.rgb("#FF0000"));

            ArrayList<IBarDataSet> dataSets = new ArrayList<IBarDataSet>();
            dataSets.add(set1);

            BarData data = new BarData(dataSets);
            data.setValueTextSize(10f);
            data.setBarWidth(0.9f);
            data.setValueFormatter(new MyAxisValueFormatter());
            mChart.setFitBars(true);
            mChart.setData(data);
            mChart.invalidate();
        }

我从github更新lib，然后我使用示例BarChartFragment来解决问题，这是我在未来遇到同样问题的人的代码：

private void setBarChart(BarChart mChart, DashboardMCOP mcop, DashboardMCOM mcom)
    {
        mChart.getDescription().setEnabled(false);
        MyMarkerView mv = new MyMarkerView(getActivity(), R.layout.custom_marker_view);
        mv.setChartView(mChart); // For bounds control
        mChart.setMarker(mv);
        mChart.setMaxVisibleValueCount(100);
        mChart.setDrawGridBackground(false);
        mChart.setDrawBarShadow(false);
        IAxisValueFormatter xAxisFormatter = new DayAxisValueFormatter(mChart,context );

        XAxis xAxis = mChart.getXAxis();
        xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
        xAxis.setDrawGridLines(false);
        xAxis.setGranularity(1f); // only intervals of 1 day
        xAxis.setLabelCount(7);

        xAxis.setValueFormatter(xAxisFormatter);

        Legend l = mChart.getLegend();
        l.setEnabled(false);

        YAxis leftAxis = mChart.getAxisLeft();

        leftAxis.setAxisMinimum(0f); // this replaces setStartAtZero(true)
        leftAxis.setEnabled(true);
        leftAxis.setAxisMaximum(100);

        mChart.getAxisRight().setEnabled(false);




        mChart.animateY(1400, Easing.EasingOption.EaseInOutQuad);
        setDataBar(mChart, mcop, mcom);


    }

SetDataBar 的

不是更改！
